In the UK property market, speed can mean the difference between winning a deal and missing out. Bridging loans provide a short‑term solution when timing is critical, but what happens if you need to borrow more than one property alone can secure? A bridging loan against multiple properties allows you to use additional collateral from more than one asset to increase the loan size or improve the terms. This guide explains how multi‑property bridges work, why investors choose them and how to approach lenders or brokers for a bridging loan quote that takes advantage of all your available equity.

When you secure a bridging loan, the lender takes a legal charge over the property or properties you offer as collateral. In most cases, this is a single house or commercial building, but it can be multiple properties—for example, several buy‑to‑let homes, flats, or a mixed portfolio that you already own. By placing more than one property behind the loan, you increase the total equity the lender can rely on, which can:

• Increase the maximum loan amount you can obtain
  
• Reduce the loan‑to‑value (LTV) ratio, making the deal less risky for the lender
  
• Potentially lower the interest rate or fees

Securing against multiple properties is sometimes called cross‑collateralisation. The lender will hold a legal charge over each property and, in the event of default, could enforce against any or all of them. For that reason, it is important to understand the structure and risks.

Adding extra security to a bridging loan is not just a way to borrow more money. There are several strategic reasons why investors and developers choose to offer multiple properties:

• Increase loan size – If the property you are buying or refinancing does not have sufficient value on its own, using another property can provide the additional equity needed to meet the lender’s criteria.
• Improve LTV and reduce cost – A lower LTV often results in a better interest rate and reduced fees because the lender has more security. This can be attractive when a project’s margins are tight.
• Unlock portfolio equity – Many investors hold equity locked in several properties. A multi‑property bridge can release capital from the portfolio without having to sell or refinance each property separately.
• Support complex transactions – Development projects, conversions or commercial purchases may require higher funding levels. Offering multiple residential or commercial properties as security can make the deal viable when a single asset would not.
• Bridge commercial property purchases – When buying a commercial building, lenders may be reluctant to lend at high LTV. Topping up with residential property security can provide comfort and unlock funds.
  

The process for securing a bridging loan against more than one property is similar to a standard bridge, with some additional steps:

1. Assess your assets and objectives – Work out which properties you can offer as security and how much equity each one has. Consider whether you are comfortable charging each asset, as all may be at risk if the loan is not repaid.
2. Discuss with a broker or lender – Present details of all properties, including addresses, current values, outstanding mortgages and rental income (if applicable). A bridging broker can help you structure the security package and find a lender who accepts multiple assets.
3. Receive indicative terms – Lenders will provide terms based on the combined value of the properties and your exit strategy. The LTV is calculated using the total loan amount divided by the combined value of all properties. A lower overall LTV typically leads to better terms.
4. Valuations and legal work – Each property offered as security will need a valuation and separate legal checks. This may increase costs because there are multiple valuations and titles to review. Some lenders allow desktop or drive‑by valuations on smaller properties to save time.
5. Funding and drawdown – Once valuations and legal work are complete, the lender releases the funds. You can complete your purchase or refinance using the combined loan.

Repayment – At the end of the term (usually a few months up to around two years), you repay the loan in a lump sum from your exit (sale, refinance or other source). All properties are released from the lender’s charge once the loan and interest are cleared.

Multi‑property bridging is not necessary for every deal. It is most useful when:

• You have a portfolio of buy‑to‑let properties and want to leverage the combined equity to fund a new purchase or development without restructuring individual mortgages.
• You need higher funds for a refurbishment or development project than a single property will allow. Offering a second or third property as collateral can make the loan possible.
• You are purchasing a commercial building and the lender requires extra security because commercial properties often carry higher risk. Using residential assets can strengthen the proposal.
• You want to reduce the rate or fees on a large loan. Even if a single property has enough value, adding another can reduce the LTV and bring down costs.

You have a complex exit that involves selling multiple units or refinancing several properties. A multi‑property bridge can align the timing of your financing, so you do not have to arrange separate loans with different end dates.

While offering multiple properties can improve terms, there are extra considerations:

• Valuation and legal costs – Each property needs its own valuation and title checks, increasing upfront fees. Make sure you budget for this.
• Cross‑default risk – If you cannot repay the loan on time, all properties offered as security are at risk. A default could affect your entire portfolio.
• Complexity – Coordinating valuations, legal work and documentation for multiple assets takes more time and organisation. A broker can help manage this process.
• Exit strategy – You must have a clear plan for repaying the loan. If your exit involves selling one or more of the secured properties, ensure the timing aligns and that you can obtain the sale price you expect. Consider backup exits in case of delays.

Potential lender restrictions – Some lenders do not accept second charge security or may limit the number of properties. You might need to find a specialist lender or broker who understands multi‑asset bridges.

• Enhanced borrowing power – Combining several properties can significantly increase the loan available, enabling larger or more ambitious projects.
• Lower LTV and improved pricing – Additional security lowers risk for the lender, often leading to lower interest rates or smaller arrangement fees.
• Portfolio flexibility – A multi‑property bridge can free equity across your portfolio without requiring separate remortgages on each asset.
• Speed and convenience – Bridging lenders can act quickly, sometimes issuing indicative terms within hours and funding within days. Securing multiple properties under one facility simplifies the process compared to negotiating separate loans.
• Versatility across property types – You can mix residential, commercial and semi‑commercial properties, which helps tailor the security package to your needs.
  

Because multi‑property bridging involves complex structures, a bridging broker is invaluable. They can:

• Access a wide panel of lenders, including those who specialise in multi‑asset bridges.
  
• Structure the deal so that the combined loan‑to‑value and security package meets lender criteria.
  
• Coordinate valuations and legal work for each property, saving you time and ensuring nothing is missed.
  
• Negotiate fees and rates on your behalf and explain how interest will be calculated across multiple securities.
  
• Provide transparency on broker commissions and ensure you understand all costs up front.

Working with a broker can make the difference between a quick, smooth funding and a frustrating process.

When planning a bridging loan secured against multiple properties:

• Identify your funding requirement and term – Be clear on how much you need, how long you need it for, and what your exit strategy is. Overestimate your timeline slightly to account for delays.
• Prepare property information – Collect up‑to‑date valuations or appraisals, mortgage statements and information on tenancy (if any). Present a clear schedule of assets and how much security each one will provide.
• Compare quotes – Ask lenders or brokers to detail interest rates, arrangement fees, valuation costs and any exit or renewal fees. Because multiple properties increase costs, compare overall fees, not just the rate.
• Understand the lender’s appetite – Some lenders only accept first charge security; others accept second charge or a mix. Check whether the loan is regulated (if any property is owner‑occupied) and ensure the lender is authorised for regulated bridging if needed.
• Ask questions – Clarify whether interest will be rolled up or paid monthly, what happens if you need an extension, and whether the lender will release security on properties you sell during the term.
  

Why would I secure a bridging loan against more than one property?

Using multiple properties as collateral can increase the total loan available, lower the loan‑to‑value ratio and potentially reduce the interest rate. It is useful when a single property does not offer enough equity or when you want more favourable terms on a large loan.

Do all lenders offer multi‑property bridging loans?

No. Some lenders prefer single security, while others specialise in portfolio loans. Working with a bridging broker helps you identify lenders who accept additional collateral and structure the deal correctly.

How does interest work on a multi‑property bridge?

Interest is usually calculated on the total loan amount and can be paid monthly or retained (rolled up) and added to the loan. The presence of multiple properties does not normally change how interest is calculated, but a lower LTV may reduce the rate.

Can I remove a property from the loan during the term?

Some lenders allow you to sell one of the secured properties and release it from the charge, provided the sale proceeds are used to reduce the loan so the remaining LTV stays within the agreed level. This should be discussed and agreed up front.

What happens if I default on a multi‑property bridging loan?

If you fail to repay the loan on time, the lender can enforce its legal charge on any or all properties offered as security. This could mean repossession and sale. A clear exit strategy and contingency plans are essential.

A bridging loan secured against multiple properties can unlock significant funding for investors, developers and business owners. By utilising additional collateral, you can increase your borrowing power, improve your interest rate and fund complex or time‑sensitive deals. However, multi‑property bridging also carries extra costs and risks, such as higher valuation fees and the potential for cross‑default. Planning carefully, choosing the right lender and working with a knowledgeable bridging broker will help ensure your project succeeds.
